The outcomes of these coin tosses Question 3: What is the probability of flipping a coin 20 times and getting 20 tails? Solution: 20 times coin tosses. Solution Problem 6: P (at least 2 heads) = Number of favorable outcomes / Total outcomes = 4 / 8 = 1/2 Therefore, the probability of getting at least 2 heads when flipping a coin 3 times is 1/2 or 50%. (It also works for tails. 1/36 b. Question 2. This means, Total observations = 2 20 (According to binomial On flipping a coin 3 times the probability of getting 3 heads, we get total eight outcomes as {HHH, THH, HTH, HHT, TTH, THT, HTT, TTT} Total outcomes are - 8 and among these three heads has one A coin is flipped 3 times. The key is understanding what the problem is asking. It does not matter if the coins are flipped sequentially or Probability of getting exactly one head or two heads = \ (3\over 8\) + \ (3\over 8\) = \ (6\over 8\) = \ (3\over 4\) Hence, Probability of getting exactly one head or two heads = \ (3\over 4\) Accurately calculate the probability of getting a specific number of heads or tails in multiple coin tosses.
